12/23:Chicago Bears running back Tarik Cohen was held to only 19 all-purpose yards in the Bears 14-9 win over the 49ers. Cohen was barely featured early on and it appeared that the speedster was being deployed as a decoy at times to run reverse plays. Cohen has been a dynamic force this season but has been vulnerable to poor fantasy performances. He will be difficult to trust in Week 17 against a tough Vikings defense that is allowing the 11th fewest fantasy points to opposing running backs and are playing for their playoff lives.--Joey C - RotoBallerSource: Chicago Bears
